A composition of matter containing water, the ammonium salt of hydroxyacetylaminophenylarsenic acid; and an alkali salt of a reducing acid.

2. A composltion of matter containing Water, the-amm0nium salt of hydroxyacetyh aminophenylarsenic acid; and an alkali salt of sulphurous acid.

In testimony whereof I aflix my signature.
